Hi All,
I have the mod installed and reloaded after edits.  My Candle Hat does not use fuel so i think it is basically OK.  I have not tried the other deployables i set to true.

The Small Generator is still using fuel.  Here is my config.  Please note i left the "Require permission...." set to false.
